LabCompanion CTU-120W Thermal Shock Test Chamber

Overview

The LabCompanion CTU-120W Thermal Shock Test Chamber is an engineered solution for accelerated reliability evaluation of electronic components, aerospace assemblies, automotive modules, and high-performance materials subjected to rapid, extreme temperature transitions. Based on the two-chamber static air thermal shock principle—comprising independent high-temperature and low-temperature zones with a vertically actuated test specimen transfer basket—the system delivers precise, repeatable exposure across a validated operational range of −55 °C to +150 °C. Unlike single-chamber ramp-based systems, this dual-zone architecture eliminates thermal inertia effects during transition, enabling true step-function thermal stress application per MIL-STD-810H Method 503.5 and IEC 60068-2-14. The chamber’s structural integrity, thermal uniformity, and dynamic response are optimized for compliance-driven validation workflows in R&D labs, QC departments, and third-party certification facilities operating under GLP, ISO/IEC 17025, or AS9100 frameworks.

Key Features

• Dual independent temperature zones (hot: +60 °C to +200 °C; cold: 0 °C to −70 °C) with mechanical lift-and-transfer mechanism ensuring ≤5-second basket transit time between zones
• High-reproducibility thermal performance: temperature deviation ≤±2 °C across full shock range (−65 °C to +150 °C); temperature fluctuation ≤±0.5 °C (per GB/T 5170.2–2017)
• Robust thermal insulation using non-hazardous, low-conductivity glass fiber (λ ≤0.038 W/m·K), minimizing energy loss and external surface temperature rise
• Industrial-grade Siemens S7-1200 PLC controller integrated with LabCompanion’s embedded PlatinumV1.0 real-time control firmware—supporting programmable dwell times, cycle counts, and multi-step profiles
• 7-inch capacitive touchscreen HMI with intuitive graphical interface, multilingual support (English, Chinese, Korean), and built-in alarm history with timestamped event logging
• Redundant safety architecture: dual independent over-temperature cut-offs, door interlock, refrigerant pressure monitoring, and emergency power-off circuit

Sample Compatibility & Compliance

The CTU-120W accommodates test specimens up to 500 mm (W) × 610 mm (H) × 400 mm (D) within its #304 mirror-finish stainless steel inner chamber—chemically inert, non-outgassing, and compatible with cleanroom-grade handling protocols. Its thermal shock profile meets the stringent requirements of military and industrial standards including GJB 150.3 (High Temperature), GJB 150.4 (Low Temperature), and GJB 150.5 (Temperature Shock), as well as international equivalents: IEC 60068-2-14 (Test N), MIL-STD-810H Method 503.5, and GB/T 2423.1–2423.2. All thermal calibration data are traceable to national metrology institutes (e.g., CNAS-accredited labs), and the system supports audit-ready documentation generation—including pre-test setup records, real-time parameter logs, and post-test summary reports—in accordance with FDA 21 CFR Part 11 (when used with optional PlatinumV1.0 supervisory software and electronic signature module).

Software & Data Management

Data acquisition and reporting are managed through LabCompanion’s PlatinumV1.0 embedded software suite. Operational parameters—including setpoints, actual chamber temperatures, basket position status, cycle count, and elapsed time—are logged at user-configurable intervals (1–60 seconds) and stored locally in comma-separated value (.csv) format via the front-panel USB 2.0 port. This interface requires persistent U-disk connection (non-hot-pluggable) to ensure uninterrupted write integrity. For networked environments, the RJ45 Ethernet port enables integration into centralized lab management systems: up to five client workstations may simultaneously monitor one chamber, while the supervisory version of PlatinumV1.0 supports hierarchical supervision of up to 32 interconnected chambers. All data exports include ISO 8601 timestamps, device serial number, and operator ID fields—enabling full traceability in regulated quality systems.

Applications

• Qualification testing of printed circuit boards (PCBs), solder joints, and wafer-level packaging under JEDEC J-STD-020 and JESD22-A104
• Reliability screening of avionics modules, flight control actuators, and satellite subsystems per ECSS-Q-ST-30-01C
• Material compatibility assessment of polymer composites, adhesives, and encapsulants used in EV battery housings and power electronics
• Validation of hermetic seal integrity in MEMS devices and medical implant housings
• Accelerated aging studies for optical sensors, laser diodes, and photonic integrated circuits exposed to field-operational thermal cycling

FAQ

What is the maximum sample weight supported by the transfer basket?
The standard vertical transfer basket is rated for a static load capacity of 30 kg. Custom heavy-duty baskets (up to 50 kg) are available upon request with structural reinforcement and recalibrated actuator torque settings.

Does the CTU-120W support nitrogen purge or inert atmosphere operation?
Standard configuration operates under ambient air. Optional nitrogen purge kits (including flow meter, pressure regulator, and sealed inlet/outlet ports) can be factory-installed to maintain O₂ concentration <100 ppm during testing—critical for oxidation-sensitive alloys and lithium-based components.

How is temperature uniformity verified and documented?
Uniformity is validated per IEC 60068-3-5 using a 9-point sensor array (per ASTM E2297) during IQ/OQ qualification. A certified calibration report—including spatial deviation maps and uncertainty budgets—is supplied with each unit and updated annually during preventive maintenance.

Can the chamber be integrated into a LIMS or MES environment?
Yes. Through the RJ45 interface and PlatinumV1.0’s OPC UA-compliant data server (optional license), real-time process variables and alarm states can be published to enterprise systems supporting OPC UA, MQTT, or Modbus TCP protocols—enabling automated data ingestion without manual export.
